is not foaming excessively, the oil return line from the
separator housing to the compressor cylinder is not
clogged or pinched off, the check valve in the oil return
line is functioning properly, and there is not water or an
oil/water emulsion in the oil.
Oil carryover malfunctions of the oil separator are usu-
ally due to using elements too long, heavy dirt or var-
nish deposits caused by inadequate air filter service,
use of improper oil or using oil too long for existing
conditions. A ruptured or collapsed separator element
is usually due to heavy dirt or varnish buildup in the fil-
tering material. Excessive tilt angle of the unit will also
hamper separation and cause oil carryover.
Oil separator element life cannot be predicted; it will
vary greatly depending on the conditions of operation,
the quality of the oil used and the maintenance of the
oil and air filters. The condition of the separator can be
determined by pressure differential gauging or by in-
spection.
Pressure Differential Gauging – The “CHANGE
SEPARATOR” advisory will flash when the pressure
differential across the oil separator reaches approxi-
mately 8 PSI. Replace the oil separator element at this
time. If ignored, the unit will shut down and the advisory
will illuminate steadily when the pressure differential
reaches 15 PSI.
Using an oil separator element at ex-
cessive pressure differential can
cause damage to equipment. Replace
the separator when the “Change Sep-
arator” advisory appears.
A sudden drop of zero pressure differ-
ential or sudden heavy oil carryover
may indicate a ruptured element.
Inspection – After removal of separator element,
shine a light inside the element to reveal areas of heavy
dirt or varnish deposits or breaks (ruptures) in the ele-
ment media.
Removal Of Oil Separator For Inspection Or Re-
placement:
Air/oil under pressure will cause
severe personal injury or death. Shut
down compressor, relieve system of
all pressure, disconnect, tag and
lockout power supply to the starter
before removing valves, caps, plugs,
fittings, bolts, and filters.
Compressor, air/oil reservoir, separa-
tion chamber and all piping and tub-
ing may be at high temperature during
and after operation.
1.
Be certain unit is completely off and that no air
pressure is in the oil reservoir.
2.
Disconnect, tag and lockout power supply to the
starter.
3.
Disconnect oil return to compressor tubing at tube
elbow near the discharge manifold flange on the
top plate.
4.
Loosen the nut on fitting at manifold flange and
completely withdraw the tubing through the fitting.
5.
Disconnect all other tubing from discharge man-
ifold.
6.
Disconnect discharge manifold pipe union.
7.
Remove screws holding the top plate to the oil
reservoir. Lift the top plate form the oil reservoir.
8.
Lift the separator from the separator housing.
9.
Inspect and/or replace the separator as
necessary. Before installing (or reinstalling) any
separator be sure gaskets bonded to the
separator flanges are not damaged. Remove the
gasket material adhering to the top plate or
reservoir flange from the old separator.
10. Lower the separator into the oil reservoir.
11. Seat the top plate to the oil reservoir flange; install
and tighten all cap screws.
12. Reconnect the discharge manifold pipe union and
all tubing.
